The capsule contains all data, analysis and results of the original research article "Overlapping identities: The role of village and occupational group for small-scale fishers’ perceptions on environment and governance".
Abstract:
Resource users’ perceptions are crucial for successful marine governance, because they affect community support, participation and legitimacy. Efforts have been made to understand how fishers’ attitudes, understandings and interpretations of the environment and its use emerge in small-scale fisheries. However, many quantitative studies have...

Matlab code for fitting a symmetric bilinear model with L1 regularization (https://arxiv.org/abs/1804.09567). This model is useful in identifying a set of small subgraphs from a large graph that contain useful information about a response. The code implements a coordinate descent algorithm to estimate the model. We attach the simulated data in the simulation study to illustrate how to use this method.

Abstract: Wandering spurs are a little-studied phenomenon seen in MASH and SQ-DDSM modulators. They take the form of frequency-modulated spurs which periodically appear in-band. Since modulators are often employed as divide ratio controllers in fractional-N phase lock loops, these spurs can feed into the output phase noise spectrum. In this paper we explain the mechanism which creates the wandering spurs, and offer a prediction for the behavior of these spurs in the MASH 1-1 modulator....

This paper deals with the problem of the classification of large-scale very high resolution (VHR) remote sensing (RS) images and in a semi-supervised scenario where we have a limited training set. Typical pixel-based classification methods are unfeasible for large-scale VHR images, and so as a practical and efficient solution, we propose to subdivide the large image into a grid of tiles, and then classify the tiles instead. Our proposed method uses the power of a...

ABSTRACT:
This work introduces a novel framework for quantifying the presence and strength of recurrent dynamics in video data. Specifically, we provide continuous measures of periodicity (perfect repetition) and quasiperiodicity (superposition of periodic modes with non-commensurate periods), in a way which does not require segmentation, training, object tracking or 1-dimensional surrogate signals. Our methodology operates directly on video data. The approach combines ideas from nonlinear time series analysis (delay embeddings) and computational...

A sound field recording and reproduction method using circular arrays of microphones and loudspeakers with a spherical baffle is proposed. The spherical baffle is an acoustically rigid object on which the microphone array is mounted. The driving signals of the loudspeakers must be obtained from the signals received by the microphones. A transform filter for this signal conversion is analytically derived, which is referred to as the wave field reconstruction filter. The proposed method using...

Conventional sub-trajectory clustering is used to identify similarities among multiple trajectories. This method has been applied to traffic routes in urban areas as well as hurricane behavior. Existing methods tend to overlook many relevant sub-trajectories; others require a road network as input; all are slowed down considerably by large datasets. In this paper, we design a novel approach to sub-trajectory clustering in which trajectories are transformed into a set of hypercubes with four dimensions. The...

Publication Summary:
Disease is both among the most important selection pressures in nature and among the main causes of yield loss in agriculture. In plants, resistance to disease is often conferred by Nucleotide-binding Leucine-rich Repeat (NLR) proteins. These proteins function as intracellular immune receptors that recognize pathogen proteins and their effects on the plant. Consistent with evolutionarily dynamic interactions between plants and pathogens, NLRs are known to be encoded by one of the most variable...

Direction-of-arrival (DOA) estimation is a problem of significance in many applications. In practice, due to the occurrence of coherent signals and/or when the number of available snapshots is small, it is a challenge to find DOAs accurately. This problem is revisited here through a new enhanced principal-singular-vector utilization for modal analysis (EPUMA) DOA estimation approach, which improves the threshold performance by first generating ($P+K$) DOA candidates for $K$ sources where $P\geq K$, and then judiciously...

Single user massive multiple input multiple output (MIMO) can be used to increase the spectral efficiency, since the data is transmitted simultaneously from a large number of antennas located at both the base station and mobile. It is feasible to have a large number of antennas in the mobile, in the millimeter wave frequencies. However, the major drawback of single user massive MIMO is the high complexity of data recovery at the receiver. In this...

A Computational Framework for Cortical Learning
Roland E. Suri*, Biological Cybernetics, https://doi.org/10.1007/s00422-004-0487-1
Recent physiological findings revealed that long-term adaptation of the synaptic strengths between cortical pyramidal neurons depends on the temporal order of presynaptic and postsynaptic spikes, which is called Temporally Asymmetric Hebbian (TAH) learning. Here I prove by analytical means that a physiologically plausible variant of TAH learning adapts synaptic strengths such that the presynaptic spikes predict the postsynaptic spikes. This hypothesis implies a...

This script performs the calibration procedure to extract k-linearization interpolation indices as well as a dispersion compensation complex window. It requires as input two interferograms from mirror measurements on either side of the zero-delay plane (one on each side). The interference signals should be corrected for background and DC.

We are given the arithmetic mean of hourly travel time measurements between different zones of a city and want to estimate the traffic flow and spatial parking distribution of cars in that city. In a first stage, we estimate the probabilities of car traffic between zones as a function of mean travel times. These probabilities exploit the changes in mean travel time between the zones of the city throughout a day to approximate information about...

We propose a linked dynamic graph CNN (LDGCNN) to classify and segment point cloud directly. We remove the transformation network, link hierarchical features from dynamic graphs, freeze feature extractor, and retrain the classifier to increase the performance of LDGCNN.

This computational notebook (written in R) runs an exploratory subgroup analysis on the SEAQUAMAT trial data. This implements and illustrates the concepts of Holmes & Watson (2018) for exploratory subgroup analysis using Machine Learning protocols with valid control of the type I error. SEAQUAMAT was a multi-centre randomised controlled trial comparing mortality between intravenous quinine and intravenous artesunate in adults with severe malaria in South East Asia. The code is as generic as possible in...

This capsule holds the code for Frangi-Net experiment on High-Resolution Fundus (HRF) Image Database.
We reformulate the conventional multi-scale 2-D Frangi vesselness measure into a pre-weighted neural network ("Frangi-Net"). Without training, Frangi-Net is equivalent to the original Frangi filter. With further training, the segmentation performance of the network is increased.

The vast majority of scientific articles published to-date have not been accompanied by concomitant publication of the underlying research data upon which they are based. This state of affairs precludes the routine re-use and re-analysis of research data, undermining the efficiency of the scientific enterprise, and compromising the credibility of claims that cannot be independently verified. It may be especially important to make data available for the most influential studies that have provided a foundation...
